The electrons are placed into atomic orbitals that determine the atom's various chemical properties. The number of neutrons in a nucleus usually has very little effect on an element's chemical properties (except in the case of hydrogen and deuterium).
According to proponents of the metabolic typing diet, the three metabolic types should eat the following foods: Protein types: Diets that are rich in protein, fats and oils, and high-purine proteins such as organ meats, pate, beef liver, chicken liver, and beef.
The initial weight loss on the Type O Diet is by restricting consumption of grains, breads, legumes, and beans. The leading factor in metabolic dysregulation leading to weight gain for Type Os is the found in wheat germ and whole wheat products, which interferes with insulin efficiency and slow down metabolic rate.
